Abstract:
The experiment was conducted in Randomized Block Design with three replications to assess the performance of 32 genotypes of cucumber to determine PCV, GCV, heritability and genetic advance as percentage of mean for various horticultural traits. The analysis of variance revealed significant differences among the genotypes for all the characters. The estimates of phenotypic coefficients of variation (PCV) were higher than genotypic coefficients of variation (GCV) for all the characters and there was narrow difference between GCV and PCV for total soluble solids, shelf life, node at which first female flower appears, number of days to first female flower production, days to first harvest, fruit length, fruit diameter, severity of downy mildew percentage and fruit yield per vine, implying that greater role was played by genotype rather than environment for expression of these characters. Moderate GCV and PCV were observed for node at which first female flower appears, shelf life, number of fruits per plant, fruit diameter and number of days to first female flower production. High GCV and PCV were observed for fruit yield per vine, average fruit weight, vine length, severity of downy mildew percentage and total soluble solids. It was observed that high heritability along with high to moderate genetic advance was observed for most of the characteristics. High genetic advance as percent of mean was observed fruit yield per vine, average fruit weight, total soluble solids, vine length, severity of downy mildew percentage and node at which first female flower appears, shelf life, number of fruits per plant, fruit length and fruit diameter.
